Considering Neural Control & Body Mechanics for the Understanding & Restoration of Human Movement
Speaker: Eric J. Perreault

Professor of Physical Medicine and Rehabilitation
The neural and musculoskeletal systems are intimately linked in the control of movement and posture. The musculoskeletal system serves as a mechanical interface between the computations of our nervous system and our ability to physically interact with the world around us. While the interdependency of these systems is obvious, there remain many scientific studies and clinical assessments of motor behavior that examine the nervous and musculoskeletal systems in isolation. Our laboratory works at the intersection of biomechanics and motor systems neuroscience, with a focus on quantifying and restoring movement control following injury. Our past work has demonstrated how intrinsic muscle properties and musculoskeletal geometry influence the neural strategies for regulating whole limb mechanics. In this presentation, I will introduce two new projects that build on that background. The first investigates the use of non-invasive shear wave elastography for quantifying intrinsic muscle properties in health and disease. The second examines challenges associatewith building neuroprosthetic interfaces that restore the volitional activation of muscles in an effort to regain arm control following paralysis.
